MPPT Solar Charge Controller

Parameter:

1. Suitable for solar power generation system
2. Constant current/constant voltage operation, with thermal regulation function, can maximize the charging rate, no overheating risk
3. Automatic low power power sleep mode when the input voltage is removed
4. Battery overvoltage protection
5. Connection is simple and easy to understand
6. Two options, needle free and needle with.For the convenience of customers, if there is no special welding tool, choose with needle, if you want to change the pin direction, choose no needle parameterMPPT Solar Controller 3.7V 4.2V 18650 Lithium Battery rechargeable 1A charger module

Description:

• 1A 5V MPPT Solar Controller for 3.7V 4.2V Lithium Ion and Lithium Polymer Batteries
• Lithium-ion battery chargers for solar power systems
• Power supply voltage DC 4.4-6V, charging output voltage DC 4.2V;
• The maximum charge current/output current is 1A, but you can change the current by changing the value of the R1 resistor.
• Automatically adjust the charging current according to the output capacity of the input power supply
• Suitable for solar power supply system
• Precharge adjustment for restoring deep discharge batteries and minimizing heat dissipation during the initial charge phase
• Constant current/constant voltage operation with thermal regulation maximizes charge rate without risk of overheating
• Automatic low-power sleep mode when the input voltage is removed
• C/10 Charge termination
• Automatic top-up
• Battery overvoltage protection
• LED indicator: “CR” LED is the charging status indicator “OK” LED full charge or constant voltage mode;
• The operating temperature ranges from -40 to +85
• The dimensions are 18mm x 10.16mm x 2.7mm
• Weight: 0.9g(with needle),0.6g(without needle)
• The on-chip adaptive battery can automatically adjust the charging current according to the output capacity of the input power supply, so the SD05CRMA is ideal for solar powered systems, or applications where lithium-ion or lithium-polymer batteries need to be recharged. An input power supply with limited output capacity.
• If your solar panel is 5V, then you can use it directly.Of course, the module can also use 5V DC power supply.
